ABSTRACT:
Introduction: Pathological tooth wear in children with primary dentition can be a result of various harmful habits, risk factors and nocturnal bruxism. It is difficult to be distinguished from physiological tooth wear.
Aim:To study caries prevalence, tooth wear prevalence, its clinical characteristics and its relationship with bruxism in children aged 3 - 7 years.
Materials and methods: The object of the study are 222 children, divided into 5 age groups - from 3 to 7 years. The examined children underwent a clinical examination, during which the following were registered: dental status, caries prevalence, the type, degree and prevalence of tooth wear. Information on the presence and characteristics of nocturnal bruxism in the examined children was obtained from the parents. The results were statistically processed with SPSS-19.
Results: Tooth wear is found in more than 2/3 of the examined children (P<0.05). The highest average number of abraded teeth is present in 6- and 7-year-old children - about 7. Tooth abrasion affects 75% of canine teeth, 37.6% of incisors and 11.8% of molars in children aged 3-7 years. The predominant severity of wear is that in the inner ½ of the enamel (degree 1b) and occurs in 41.7% of children (P<0.05). 1/3 of the examined children have nocturnal bruxism (P<0.05). In almost 90% of them, tooth wear was found (P<0.05).
Conclusions: There is an increase in the severity of tooth abrasion with age in children between 3-7 years. Nocturnal bruxism is almost always accompanied by tooth wear.
